Dynatriax System - Triaxial System

Triaxial System - Dynatriax System for Soil Analysis

The Triaxial System - Dynatriax System for Soil Analysis system reproduces vibration, shock and cyclic forces applied to the soil samples in the laboratory such that the engineers have a better understanding of how a soil behaves in these conditions. It is a Servo Pneumatic system designed to perform static and cyclic stages of a Triaxial test.

Base system includes a triaxial load frame 50kN (11000lbf) or 100kN (22000lbf) capacity, fitted with a double acting pneumatic actuator ±5 kN (1100lbf) or ±14 kN (3000lbf) which can generate frequencies of up to 70 Hz; data acquisition, process and control system; control Software for saturation, consolidation, stress path, monotonic and cyclic shear stages; personal desktop computer

The Triaxial System - Dynatriax System for Soil Analysis is the only pneumatic system which covers most requirements with three axis control for axial load or displacement, cell pressure and back pressure, user defined wave shapes, Automatic performance of 24 hours 7 days test to maximize the efficiency of the equipment, etc. and meets  ASTM D 5311; ASTM D 3999; and other international standards.

The dynamic triaxial system developed using the latest technologies and decades of experience in the dynamic soil testing field, is ideal for commercial and research laboratories.
